perf-marks - npm Package Versions

[1.12.0][] - 2020-07-31

Added

• Adding entry points checks in bundlesize task
• New method profiler() to profile functions using perf-marks. The idea here is to avoid boilerplates on consumer's side by having an easy way to do that. So instead of doing this

import { start, end } from 'perf-marks/marks';
const markName = 'name-of-the-mark-for-this-method';

const methodToBeMeasured = () => {
  /** method content */
};
// ...
start(markName);
const data = methodToBeMeasured();
const mark = end(markName);
return { data, mark };

The consumers can have same effect by doing this

const methodToBeMeasured = () => {
  /** method content */
};
// `res` will contain `mark` with the information and `data`
// if `methodToBeMeasured` returns something
const res = profiler(methodToBeMeasured, 'name-of-the-mark-for-this-method');

Fixed

  • isUserTimingAPISupported: Boolean with the result of the check if User Timing API is supported for the current browser/NodeJS version

Added

import * as PerfMarks from 'perf-marks';

...
// Checking if `PerformanceObservable` is supported for the current browser/NodeJS version
if (PerfMarks.isPerformanceObservableSupported) {
  try {
  // If yes, start the PerformanceObserver
    const observer: PerformanceObserver = new PerformanceObserver(list => {
      // ... Do something
    });

    // register observer based on the entryTypes
    // E.G. for long task notifications
    observer.observe({ entryTypes: ['longtask'] });
  } catch (e) {}
  // ... Finishing the observer
  observer.disconnect();
}
